Funny, that would have been more credible if she had posted the link to said photo, because the photoshopped version seems to have originated from her account.
She certainly doesn't need Photoshop, but apparently she thinks so. Also, a professional mag would certainly not have made the other models' bodies look bigger. Her selfies are also often photoshopped at the waist, while she is already thin as can be. It's kind of sad, really. Includies the fact that she lies to cover for herself.
